The document describes an acoustic listening platform called VIVID that provides full bandwidth acoustic sensing from 300Hz to 656kHz, allowing it to evaluate downhole fluid movement with unprecedented clarity. By utilizing its industry-leading sensitivity across the full acoustic frequency spectrum, VIVID can detect small fluid flows and precisely identify flow depths, helping operators diagnose tubing, casing, and zonal isolation issues without pulling the completion.

1. Acoustic Listening Platform
Full bandwidth - full information.
With its industry leading sensitivity and
unparalleled frequency bandwidth, VIVID brings
clarity to downhole fluid movement evaluation.
Combining innovative sensor technology with
interactive processing, Archer’s next generation
acoustic listening platform expands the envelope
to encompass a frequency range all the way from
audible up to high frequency ultrasound, creating
the first truly broadband listening platform.
Specifications:
Frequency range : 300Hz – 656kHz (2 sensors)
Outer diameter : 1-11/16”
Max. operating Temp: 177degC
Max. operating pressure: 15,000psi
Applications:
- Barrier leak detection in tubing, casing and
completion components
- Detection of fluid flows behind pipe
- Evaluation of cross-flows
- Appraisal of sealing performance of cement
barriers
Sensitivity and precision
Utilizing the full acoustic frequency spectrum allows detection of small signals behind multiple casing
strings, while the known properties of ultrasound allow very precise depth information. High sensitivity
allows detection of very small fluid flows, even in cement where conventional bond tools indicate zonal
isolation
3 elements:
1) Operating optimization
2) Reservoir performance
3) Well integrity
Key Benefits
- Diagnose tubing, casing and zonal isolation
failures without pulling the completion
- Precise identification of fluid movement depths
- Spectrum analysis allows characterization of leak
behavior
